CVE-2004-1473 describes a filtering bypass vulnerability in Symantec Enterprise Firewall/VPN Appliances (firmware before 1.63) and Gateway Security products (firmware before 622). Remote attackers can exploit this by conducting a UDP port scan with a source port of UDP 53 to determine if services like tftpd, snmpd, or isakmp are running, effectively bypassing intended filtering. This vulnerability has a CVSS score of 5.0, indicating a medium severity. It requires no authentication or complex attack methods (AV:N/AC:L/Au:N) and primarily impacts confidentiality (C:P), allowing information disclosure without affecting integrity or availability. There is no evidence of active exploitation, and no public exploit code exists in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage are minimal, suggesting low public awareness and attention for this older vulnerability.
